The eternal war between math and code in one factorial joke! In programming, 2!
is just a very excited 2
(or a boolean NOT applied twice, returning the original value). But for mathematicians, 2!
is factorial notation meaning 2×1=2.
The programmer's horrified "No" versus the mathematician's smug "Yes" perfectly captures why we can never have nice things in cross-disciplinary meetings. And why commenting your code matters—unless you enjoy watching your math friends have aneurysms during code reviews.
